I'm trying to imaging how can it runs with /dev/null device. But the problem is if we can use at the same way than Mysql. If you truncate a table after every 'action', those truncates will appear in the Wal, so it couldn't be replicated the inserted data. Maybe could be usefull for test configuration in pgsql way.
